Specification of Letters Patent.

Patenten nl? -1 ,application led May 15, 1914. Serial No. 538,7S.

To all if/:imm it may concern lie it known that l, SAMUEL A. DUGAN, acitizen of the United States, and a resident of ('alveston, in thecounty of Galveston and State of Texas, have invented a new and improvedLocomotive Engine Cnt Out 1falv'e, of which the following is a full,clear, and eXact description.

This invention relates to locomotives and deals more especially `withvalves for cutting out either engine of the locomotive under certainemergency conditions whereby the locomotive can still be run to a pointof repair or to the end of the route.

to improve and simplify the construction of valve mechanisms of thecharacter referred to so as to be thoroughly reliable and efficient inuse and comparatively simple and inexpensive to manufacture nd withoutrequirino" any change in the standard design of piping or smoke boxconstruction.

l further object of the invention is the provision of a valve in'eaclibranch of the `r-coupling between the dry pipe and branches that lead tothe locomotive engines, whereby either one of the latter can be cut outof use in case of a breakdown of.

such engine. y

Another object of the invention -is the provision of means whereby thevalves can he operated from the locomotive cab so that the valves cannotonly be conveniently ma- 35 nipulz'itecl but they may be used forcont-rolt the point Where the dry pipe cnes to tlie fngines, so that atthe end 1 or when theloconiotive is-to be put ni glit,tlie branches orbreeches pipe ,sed so that Water of condensation ect is the provision ofcutdrain into tbe engine cylinders and ate tne removing of tbevv ferofc-onfrom sii-'fn cylinders .vnen the lco ooiects in view, ann others iappear as the description proinvent-ion comprises various novel actionand arrangement of be set forth Wit-li particuollovvin' description andto be again neen. E

The invention has for itsgeneral objects' install =ing the running ofthe locomotive when the ttle valve is nnserviceable for any dry pipe, Fand F the branches and breechesof the dry pipe that lead to the enginesof the locomotive, and G the Y-coupling that connects the dry pipe withthe branches.'

All of the foregoing parts are of-usual construction witli the exceptionof the coupling G. i

The lateral branches g and g or" the Y- coupling are each formed with apartition l in which is a valve seat 2, and. arranged to engage the seat2 is a valve 3 fastened to a stem e that is operated in any suitablemanner to open and close the valve from a point outside the smokechamber B. ln the present instance the stein 11- passes through astutling box 5 and has a screw i5 which is engaged by a nut 7, said nutbeing rotatably mounted in a bearing 8 of the bracket 9 or othersuitable support mounted on the Y- coupling. G. By turning this nut 7the valve stem 4l is moved longitudinally to open or close the valve 3.Under normal condi-v tion the valves of both branches of the Y- couplingG are open, so that steam flow to the engines of the locomotive,according to the manipulation of tbe tiirol'tle valve by the engineer.lf, lio-Wever; piston or cylinder, linlr motion or driving-j connectionsof any engine are deranged, 'Llie envi cut that engine ont of service byvalve S therefor continue to drive the locomotive by using the otherengine.

lt .is preferable to provide n ans whereby the engine cut-ont valves mayhe operated 'from the engine cab lil, and for this purnose a shaftl;entends frein each valve to the cab, and on the rear end of each shaftis a handivbeel or equivalent operating means ll, and on the front endof each shaft is a bevel gear l2 which Ineslies with bevel gear lfas;-ned to the 'ont 7 for the associated v ive 3. Not only are theengine cnt-out valves useful in case of a breakdown of an engine, butwhen the locomotive is to be put away for the night the valves 3 can beclosed before the engineer leaves his cab, and thereby Water ofcondensation is prevented from draining into the engines.

From the foregoing description taken in connection With the accompanyingdrawing, the advantages of the construction and method of operation willbe readily understood by those skilled in the art to which the inventionappertains, and while I have described the apparatus which I nowconsider to be the best embodiment thereof, I desire to have itunderstood that the apparatus shown is merely illustrative and that suchchanges may be made when desired as are Within the scope of the appendedclaims.

.Having thus -described my invention, I claim as new and desire tosecure by Letters Patent:

l. In a locomotive, the combination of 'driving engines, a boiler, ahorizontallydisposed dry steam pipe, a smoke-bex into Which the pipeextends, 'branches in the smoke box and leading from the pipe to theengines, a Y-coupling uniting the branches With the dry steam pipe., andvalves in the Y-coupling for opening and closing the sup` ply of steamto the branches.

2. In a locomotive, the combination of driving engines, a dry steampipe, branches connected With the engines, a Y-coupiing uniting thebranches with the dry steam pipe, valves in Ythe Y-coupiing for openingand closing the supply of steam to the branches, and means connectedwith the respective valves and extending to the locomotive cab forpermitting the vaives to be cperated by the engineer.

boiler, pipes in the smoke box and connected with the dry steam pipe,driving engines receiving steam from the branches, and sep-- aratevalves at the points oi, linien of the branches of the dry steam pipewhereby either or both branches may be closed.

'4. In a locomotive, the combination of a boiler, a smoke ox, a drysteam pipe 'in the boiler, pipes in the smoke box and con` nected Withthe dry steam pipe, driving engines receiving steam from the branches,separate valves at the points of union of the branches of the dry steampipe whereby either or both branches may be closed, and an operatingmechanism for each valve and including means extending to the cab of thelocomotive.

In a locomotive, the combination of driving engines, a boiler, a smokebox, a dry steam pipe in the boiler, branch pipes connected with theengines, a Y-conpling connecting the upper ends ofthe branches with thedry steam pipe, valves inthe con-- pling for openingand vclosing thecommunication between the' branches and dry steam pipe, stems on thevalves extendirg out of the Y-coupling and out of the smoke box,

and. operating shafts operatively connected with the valve stems andextending to the cab of the locomotive. Y

In testimony whereof I have signed my name to this specification in thepresence of.

tivo subscribing witnesses.
